BLUING DEVICE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed November 30, 19b9,. Serial No. 465,039.

To all whom it may concern:

Be it known that we, ABRAHAM L. WVILL- COCKS and ALFRED P. THORLEY,citizens of the United States, residing in the borough of Manhattan,city, county, and State of New York, have invented certain new anduseful Improvements in Bluing Devices for Laundry Purposes, of which thefollowing is a specification.

Our invention is designed to afiord a cheap but effective holder forbluing for laundry purposes, by means of which pure coloring matter maybe used in powdered form in such manner that only the solution thereofcan enter the bluing water. Ne thus, by preventing the escape ofundissolved coloring matter into the bluing water, not only prevent thestreaking or discoloring of the linen treated therein, but also enablethe user to economize in the quantity of bluing used, at the same timeavoiding the necessity of contact with the bluing mate rial or with theconcentrated solution of coloring matter as it escapes from the holder.Furthermore, we guard against discolorization of extraneous objects bydrip from the holder after use, and attain other practical advantageshereinafter enumerated.

Our invention consists essentially of an original package formed of aporous bag or cartridge, containing soluble bluing material, inclosed ina stiff perforated shell pro vided with a handle, substantially ashereinafter described and claimed specifically, an incidental featurebeing the provision of an anti-drip space at the bottom of thereceptacle.

In the accompanying drawings, Figure 1, is a side elevatlon of ourimproved bluing device; Fig. 2, a top view thereof; Fig. 3, alongitudinal section of the same, the handle being shown in elevation;Fig. 4:, is a bot tom view of the device; Fig. 5, an end view thereof;Fig. 6, a view similar to Fig. 3,

showing a modification of structure; Fig. 7, a transverse section uponplane of line 77 Fig. 1, the cartridge being omitted.

Our device for bluing water for laundry purposes consists primarily of aporous bag or cartridge C, containing indigo, Prussian blue or othersoluble coloring matter used in laundry work for counteracting theyellow tinge of linen, and a stiff perforated shell S inclosing saidcartridge and provided with a suitable handle 8.

The shell S is preferably, although not necessarily cylindrical inshape, and is formed with a series of holes 8, in its ends, sides andtop portion, but not at the bottom, which is imperforate to form ananti-drip trough a, below the level of the line to, ca, shown in Figs.3, 6 and 7, to hold and retain any residual moisture contained in thecartridge after the shell has been removed from the water and drainedmore or less. This is to guard against drip that might otherwise soilextraneous objects.

The handle 3, is preferably madein the form of a loop by which thedevice may be hung in an upright position when not in use, thuspreventing the escape of the solution contained in the anti-drip trougha.

he handle is also of sufi'icient length to provide for the convenientmanipulation of the device without hand contact with the shell or water.

Being designed as an original package, to be discarded after thecontained bluing material has been dissolved away, the ends of the shellmay be forced into the body as in Fig. 6, or onto the body portion as inthe other figures of the drawings or otherwise constructed as may befound most expedient.

By the use of the porous bag or cartridge C, we are enabled to use purecoloring matter in powdered form, thereby avoiding the objectionablebases or binders employed when the coloring medium is prepared in theform of cakes, balls or other solid structure,such bases or bindersbeing objectionable not only as impurities, but also because they areliable to streak and discolor the linen immersed in the water in whichthey are dissolved with the bluing.

By our invention we promote cleanliness, economy of coloring matter, andpurity of color; and are enabled to use powdered material which willdissolve quickly. Furthermore the coloring material can escape from theshell only when and as dissolved by the water in which it is immersed,the porous bag or cartridge permitting the solution to percolate throughit, but efiectuallyretaining the *undissolved powder.

The cost of the device as an original package is compensated for by theeconomy of coloring matter attained, as well as by the other advantagesof cleanliness and convenience.

l/Vhat we claim as our invention and desire to secure by Letters Patentis,

An original package of the character described consisting of a porousbag containthe anti drip trough as and for the purpose ing a solublecoloring matter, a stifi cylinset forth.
